Onset RXW-THC-868 HOBOnet Temp/RH Sensor (-40°C~75°C; 0–100% RH)

868MHz

Temperature:

Measurement Range: -40°C to 75°C (-40°F to 167°F)

Accuracy: ±0.25°C from -40° to 0°C (±0.45°F

from -40° to 32°F); ±0.20°C from 0° to 70°C (±0.36°F from 32° to 158°F); ±0.25°C from 70° to 75°C (±0.45°F from 158° to 167°F)

Resolution: 0.02°C (0.036°F)

Response Time (typical, to 90% of change): Without solar radiation shield: 3 minutes, 45 seconds in air moving 1 m/sec; With RS3-B solar radiation shield: 6 minutes, 30 seconds in air moving 1 m/sec

RH:

Measurement Range: 0–100% RH at -40° to 75°C (-40° to

167°F); exposure to conditions below -20°C (-4°F) or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1%

Accuracy: ±2.5% from 10% to 90% RH typical to a maximum of ±3.5% including hysteresis at 25°C

(77°F); below 10% and above 90% ±5% typical

Resolution: 0.01% RH

Response Time (typical, to 90% of change): Without solar radiation shield: 15 seconds in air moving 1 m/sec; With RS3-B solar radiation shield: 30 seconds in air moving 1 m/sec

Operating Temperature Range: -25° to 60°C (-13° to 140°F) with rechargeable batteries; -40° to 70°C (-40° to 158°F) with lithium batteries

Logging Rate: 1 minute to 18 hours

Battery Type/ Power Source: Two AA 1.2V rechargeable NiMH batteries, powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40° to 70°C (-40° to 158°F)
